    ArrayList as a property

    Tom Newbie

      2 quick edits/additions:

      The value of node 3 is 'fourth msg,' not 'fourth value' as reported. My error transcribing (it is the fourth value, after all...: )

      Second, when creating/configuring the cache, I use the example config file:

      _distributedCache = new TreeCacheAop();
       config.configure(_distributedCache, "etc/replSync-service.xml");
       _distributedCache.setTransactionManagerLookupClass("org.jboss.cache.DummyTransactionManagerLookup");
       _distributedCache.start();
       System.out.println("Distributed cache created");


      which is:

            Hi,

            I have checked your problem. This is a bug in CacheListIntereptor.remove(). I have fixed it. But since I am currently in the process of fixing some other bugs there, I won't check it in maybe unitll next week. Will let you know.

            Thanks,

            -Ben

              BTW, this bug has been fixed and code will appear in the upcoming 1.0 pach.

              Thanks,

              -Ben
